Okay, maybe that last one isn't so normal. It's a little weird (and awkward) to spend her Sundays talking periods, B. O., and pimples. But Elsie's also learning a lot more than she's heard in her public-school health class -- like the difference between sex and gender, and what consent is, and what it might mean that she can't stop blushing around a certain cute girl at her school.

When her puberty lessons become the school's latest gossip, Elsie's totally humiliated... until she finds an anonymous note in her locker from a classmate who wants to know more, and realizes that other kids might have embarrassing questions of their own.

Starting an underground advice board wasn't exactly in her plans, but Elsie won't pass up a chance to turn her reputation around -- or to share words and labels that have not-so-accidentally been left off their curriculum. But when the principal tries to shut down the unauthorized puberty talk, Elsie has to decide what she's willing to risk to tell the truth to kids who really need to hear it.
